Abstract: The present disclosure relates generally to systems and methods for testing and determining a corrective lens prescription for a patient. In an example embodiment, a method includes receiving, in a remote device, a link to enable a patient to launch an interface on the remote device for interacting with a patient terminal in a hand held manner. The interacting includes receiving instructions from a server and enabling the patient to make at least one input to the server via the remote device over a communication interface to control the first computerized screen from a distance. The method also includes displaying a figure on the first computerized screen and enabling the patient to make a least one input via the remote device to change a size of the figure. The input corresponds to a sphere measurement of the patient.

Abstract: The present disclosure relates generally to systems and method for testing and determining corrective lens prescription for a patient. In an example embodiment, a system includes a hand-portable first electronic device, a second electronic device with a computerized screen, and a server to conduct a vision test for a person. The vision test includes determining, an axis prescription, a cylinder prescription, and a sphere prescription for each eye of the person. A corrective lens prescription is provided for the person based, at least in part, on the determined axis, cylinder, and sphere prescription for each eye of the person.

Abstract: The present disclosure relates generally to systems and methods for determining the refractive error of a patient, more particularly determining the patient's refractive error by using a computerized screen, and providing a prescription for the patient's preferred type of corrective lenses. In a general embodiment, the present disclosure provides a method for determining a corrective lenses prescription of a patient. The method includes, separately, for each eye of the patient, determining an astigmatism prescription for the patient via a computerized screen and without the use of a refractor lens assembly, including instructing the patient to move a known, fixed distance away from a computerized screen and testing for a cylinder component by sequentially presenting at least two cylinder diagrams to the patient via the computerized screen and enabling the patient to select at least one input per cylinder diagram, where those inputs correspond to cylinder measurements for determining the prescription.

Abstract: The present disclosure relates generally to a system and method for testing and determining a visual field of a patient. In an example embodiment, a method includes instructing a computerized screen to display to a first visual field diagram to a patient, wherein the first visual field diagram includes a selected portion and instructing the patient to focus on the selected portion of the first visual field diagram. The example method also includes modifying the first visual field diagram to temporarily display an additional feature in an area corresponding to a part of the patient's visual field and receiving an input indicative that the patient saw the temporarily displayed additional feature. The example method further includes determining that the patient has vision in the part of the patient's visual field corresponding to the area in which the temporarily displayed additional feature was displayed based on the received input.

Abstract: The present disclosure relates generally to a system and method for determining the pupillary distance of a person, more particularly determining the person's pupillary distance by using a computerized screen. The system and method do not require the trip or expense of a doctor or store visit, and are optimized for convenience and cost effectiveness. In a general embodiment, the present disclosure provides a method for determining a pupillary distance of a person without physically measuring the pupillary distance with a device. The method includes receiving a front facial image of the person, determining a scale of the image based on an estimated canthal distance, and determining the pupillary distance of the person based, in part, on the determined scale of the image.

Abstract: A golf club includes a shaft and a head attached to the shaft. The head has forward and rear ends and a ball-striking face positioned adjacent the forward end. The golf club is also provided with a movable member having a propellant charge therein. The movable member is positioned in the head and is movable between a first position, in which it is positioned adjacent the rear end of the head, and a second position, in which is it positioned adjacent the front end of the head. A detonating mechanism is provided for detonating the charge when the movable member moves from its first position to its second position during the movement of the head. The charge causes the head to accelerate in a generally forward direction when the charge is detonated by the detonating mechanism.
